The quasihole states of several paired states, the Pfaffian, Haldane-Rezayi, and 331 states, which under certain conditions may describe electrons at filling factor ν = 1/2 or 5/2, are studied, analytically and numerically, in the spherical geometry, for the Hamiltonians for which the ground states are known exactly. We also find all the ground states (without quasiparticles) of these systems i...

In a 331 model in which the lepton masses arise from a scalar sextet it is possible to break spontaneously a global symmetry implying in a pseudoscalar majoron-like Goldstone boson. This majoron does not mix with any other scalar fields and for this reason it does not couple, at the tree level, neither to the charged leptons nor to the quarks. Moreover, its interaction with neutrinos is diagona...

Atomic structures of the reconstructed Si~113! surfaces were studied by using Kikuchi electron holography ~KEH!. Three-dimensional images show clearly the characteristics of the puckering model for both Si~113!~332! and ~331! surfaces. The KEH results support the puckering model. Based on our studies, the tetramers are puckering alternatively in the ~332! surface. Whereas in ~331! structures, t...

Mycosporine-like amino acids (MAAs) were extracted from a unicellular cyanobacterium (Euhalothece sp.) isolated from a gypsum crust on the bottom of a hypersaline saltern pond in Eilat, Israel. When grown at high light intensities, this isolate contained high concentrations of two MAAs, one showing maximum optical density at 331 nm and one at 362 nm. The compound absorbing at 331 nm was purifie...
